Example 1: To convert the following values into degrees:
radians=90
°, 50 grads = 45°
The following procedure assumes that the calculator’s default
angle unit is degrees.
(π)
DRG ► (
r
)
(DRG ►)
(g)
Example 2: cos(π radians) = -1, cos (100 grads) = 0
(π)
(DRG ►) (r)

Example 3: cos
-1
(-1) = 180
cos

Exponential Functions and Logarithmic
Functions
• For the logarithm function ”log(“, you can specify base m
using the syntax “log (m,n)”.
If you input only a single value, a base of 10 is used for the
calculation.
